Specification of Letters Patent.

Patented Aaug. 3, 1916.

.To all whom t may concern.'

Be it known that I, HARVEY S. Bomen, a citizen of the United States, residing at Detroit, in the county of Wayne and State of` Michigan, have invented a'new and useful Improvement in Gearing, of which the following 1s a speciiication.

This invention relates to gearing` espe-l cially designed for operating a self-waiting table of the kind provided with two rotatable tops, arrangedconcentrically with respect-to'each other, and which are separably rotatable, together with common means for rotating either the inner or outer top portions at pleasure.

The invention also consists in the novel features of construction hereinafter de-,

a handle being broken away, and, Fig. 4 is a top plan view of the outer end portion of the operating mechanism.

It will be understood that a circular table is employed, and that it is provided with four supporting legs 1, arranged ninety Vdegrees apart and three of which appear in Fig. 1. The table top consists of inner and outer circular rotatable portions 2 and 3prespectively, and I prefer to have the inner portion 2 slightly elevated above the outer portion 3. The operating mechanism is carried beneath the top 2, and in practice will be hidden from view by means of suitable panels 4 which run from one table leg 1 to the other, one of said panels being shown in section in Fig. 1 and a vertical edge o-f an adjacent panel being indicated by dotted lines upon the right-hand side of Figs. 1 and 2.

As the invention consists essentially in the means for supporting and independently rotating the tops 2 and 3 it has not been considered necessary to illustrate in detail the features which are purely ornamental in character. Upon a suitable supporting brace 5 connected at its ends to two of the table legs is a suitable ball bearing 6 for a shaft receiving socket 7. A bracket S is also carried by the brace 5 and forms a lower bearing for a shaft' 9, the lower end of which is engaged with the rotatable socket 7. The outer table top 3 is provided with a suitable apron 3a and is supported and travels upon suitable anti-friction balls 10 carried in suitable ball cups 11 which are mounted upon the tops of the table legs. The top portion 3 also carries angled and radially extending brackets 12. These brackets intersect at the center of the table and form also a bearing for the shaft 9. These brackets carry a beveled gear wheel 13. Suitable intersecting brackets 14 also run from the panels 4 and midway the table legs 1 and at their point of intersection furnish a further support for the shaft 9.

Immediately below the brackets 14 a small beveled gear 15 is fixed upon the shaft 9, the gear 13 being loose upon the shaft. .t will be obvious that if the gear 13 is rotated, rotation will be given tothe top portion 3, whereas if the gear 15 is rotated the top 3 will remain stationary and rotation will be imparted to the elevated top section 2. To operate these gears by a. common mechanism I employ the following described construction: A shaft 16 is horizontally journaled in one of the table legs and its inner end is also supported by a. suitable bracket 17. Mounted upon the inner end of the shaft 16 is a beveled gear 18 adapted to be brought into mesh with the gear 15. A. spring 19 is coiled about the shaft 16 and arranged between the gear 18 and the bracket 17. rl large beveled gear 20 is also fixed upon the shaft 16 and is provided with a grooved hub 21. Upon the outer end of the shaft is a handle 22 and between the handle and the table leg is loosely mounted a flanged collar 23, a coiled spring 24 being interposed between the table leg and the collar 23, intended to normally slide the collar 23 toward the handle 22. The hub 21 is connected to the collar 23 by a suitable bar 25 which also works through the table leg, the gear wheel 2O being slidably keyed to the shaft 16. A suitable button 26 is pivotally carried by the collar 23 and when thrown into parallel relationship with the shaft 16 spaces the collar 23 from the handle 22 comprising the spring 24, and holding the gear 20 in mesh with the gear 13. Rotation of the handle will therefore rotate the gear 13 and the top 3. It will be noted that the bar 25 is suitably notched to engage both the hub 21 and the Collar 23 and the hub 21 rotates freely with respect to the bar 25 and the collar 23 remains stationary. Vhen it is de sired to rotate the shaft 9 and the top portion 2 carried by said shaft itis simply necessary to lift the button 26 and press inwardly upon the handle 22. The spring 24 pressing outwardly will slide the collar 23 away from the table leg 1 and the bar 25 will draw the beveled gear 20 out of engagement with the gear 13. At the same time the lifting of the button 26 permits the spring 19 to'move the gear 18 into engagement with the gear 15., The brackets 12 also serve as suitable supports for cups 27 within which are arranged balls 28 upon which the top 2 turns. -The top 3 is provided with a suitable bolt 29 by means of which it can be locked against rotation if desired, the bolt engaging the top of the table leg through which theshaft 16 passes.

It will be obvious that many modifications can be made in the form of the parts and especially in the arrangement of braces and supporting means without in any way changing the essential features of the invention or materially effecting the results sought.

What I claim isz- 1. Gearmechanism comprising a vertical rotatable shaft, a horizontal member supported thereby, a horizontally arranged gear loose on said shaft, a horizontal member for Supporting said loose gear, a slidable horizontally arranged shaft, means for sliding said shaft, means for locking said shaft against sliding movement,` and means carried by said horizontal shaft for transmitting rotation to the loose gear when the horizontal shaft is locked andmeans for disengaging said rotation Vtransmitting means from the loose gear when the horizontal shaft is unlocked.

2. Gear mechanism comprising a verticalV shaft, a rotatable member mounted concentrically therewith, a gear supported by said rotatable member and loosely mounted on the shaft, a horizontal longitudinally slidable shaft, an operating crank fixed to the outer end thereof, a gear and collar slidably mounted on the horizontal shaftfa connecting link for the said gear and collar, means for normally holding the gearsV out of mesh7 and means carried by the collar adapted to engage the shaft crank for shifting the gear on the horizontalV shaft into engagement with the gear on the vertical shaft.

3. Gear mechanism comprising right-angularly disposed shafts,a gear and rotatable meansfor supporting the same loosely mounted on one of said shafts, a gear and collar slidably mounted on the other shaft, connecting spacing meansfor the gear and collar, coperating means carried by the collar and last-named shaft for Vholding the gears in engagement, and means for disconnecting the gears when the cooperating means is inoperative.
